CHLA Clinical Research Studies

Having volunteers participate in research studies and clinical trials is critical to our research efforts. Thousands of children and families are involved in our patient-centered studies every year. Many of the treatments used today are based on the results of past research studies and clinical trials conducted with our patients. Our scientific and clinical experts take the best ideas from the laboratory -- to the patient -- in the form of promising new treatments.

By searching our study directory, you may identify research that could impact the life of your child or of another child you know. Because the number of available research studies and clinical trials for children nationwide is small, every participant makes a significant contribution.

In addition to enrolling children with certain diseases in order to study treatments and prevention of those diseases, we also need to study healthy children. Ask your child’s doctor about volunteer study options that may be suitable for your child.

Study Details - ID: CHLA-16-00229
Health/Science/Disease Category:
Healthy Mothers and their Healthy Infants Needed
Purpose of Research:
We are studying how responses to the rotavirus vaccine are influenced by infant nutrition and other exposures in different areas of the world. The information we get from this study may help us to understand how to best protect infants from rotavirus and other infections.
Short Name:
Breast milk, infant microbiome and responses to oral rotavirus vaccine in multiple geographic locations
Full Title of Study:
Characterization of the breast milk, infant oral and gut microbiomes in multiple geographic locations; role in immune development and response to oral rotavirus vaccine
Phase/Type of Study:
Healthy mothers 18 years of age and older and their healthy infants up to 2 months old scheduled to receive the rotavirus vaccine as part of their routine vaccination schedule
Time Commitment/Requirements:
Participation will last up to 36 months; up to 10 visits will be performed.
